Coniferous forest soil and its organisms were used as test objects, in addition, how a short- term low temperature period including frost affects respiration dynamics in stressed soils was studied, i.e., whether contaminants reduce resistance of the community to other (also natural) stres- ses. In addition, at the end of the experiment, effects of con- taminants on faunal and microbial community structures were analyzed. 收起
